SUPPORT FOR spmNine-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 376,234, dated January 10, 1888.

I Application tiled December 21, 1886. Serial No. 122,172. (No model.)

To @ZZ 1.071.011@ it may concern:

Be it known that l, WILLIAM T. CARROLL, of Worcester, county of Worcester, and State of Massachusetts, have invented an Improvement in Supports for Spinning-Spindles, ot" which thefollowing description, in connection with accompanying drawings, is a specification, like letters on the drawings representing like parts. iO Prior to my invention bolster-hearings for that classofspindleshavingasleeve-whirl have been mounted loosely in a rigid support, the holster-bearing being surrou nded sometimes by an elastic packing and sometimes by oil, which i 5 .constitutes a cushion; and so, also, the bolsterhearing for this kind of spindle has been made rigid, and such holster-hearing has been slipported loosely upon or with relation to the holster-rail, so that the said bearing might move bodily, thus doing away with the separate or independent holster surrounded by either packing or oil.

In my present invention the bolster-hearing is extended through a hole in the holster-rail, which hole it enters loosely, and a part of the holster is arranged to co-operate with one or more yielding holders, the said holders cooperating, preferably, with two or more of the bolster-bearings when vihrated, by reason of the strain of the spindle within the said holster-bearings, .the said spindle being in rotation and being unevenly loaded.

My invention consists, essentially, in the combination, with a bolster-rail provided with g5 a hole and a bolster having its shank extended through the said rail loosely, of a flexible holder co-operating with one or more of the said holsters outside of the said rail to restrain their motion within certain limits when the said holsters are made to vibrate or move laterally by reason of the strain of the spindles Within them. This holder may also restrain the holster-from rotating with the spindle.

Figure 1 in side elevation represents a sufmy invention to he understood. Fig. 2 is a detailed elevation of the foot of one of the holster-bearings shown in Fig. l; Fig. 3, a detailA showing a portion ofa spinning-frame contain- 5o ing a modifiedr form of my invention; Fig. 4, a detail showing in elevation the foot of one of licient portion of a spinning-frame to enableV -of a tube-like extension, which receives within it the spindle B, and in turn is surrounded by 6o the sleeve-whirl of the spindle. This holster has a suitable shoulder or collar, as a, to determine theposition of the bolster with relation to the rail A. The rail A has a series ot' Y holes-one foreach holster-the said holes heing alittle larger in diameter than the diameter of the bolster externally, so that when the holsters are inserted in the said holes they have freedom of motion to a limited extent.

I have done away with all packing such as 7o heretofore commonly used to surround the bolster-hearing, and instead I have notched or cut away the bolster-hearing to receive in the said notches a iieXihle holder, b, which for the best results will be either a iiexible wire or rod, as shown in Figs. 1, 5, and 7, or a cord, as shown in Fig. 3.

The holder shown in Fig. l is connected at one end to a stud, b', attached to the bolsterrail, and at the other end to an adj ustahle 8O lscrew-stud, b2, extended through a lug, b3, at-

tached to the bolster-rail, the said holder heing embraced by the forked or notched part, as

2, of the foot or shank c of each holster, or'of two or more holsters, the diameter of the said holder and ofthe slot beingpreferahly of such size one with relation to the other as to permit of slight movement of the foot of the holster withoiit coming in Contact with the said holder;r hut as soon as a contact between the go bolster and holder is made the holder thereafter acts as a check to the undue vibration of the holster, and also acts as a cushion for the bolster, and prevents at the same time the rotation ofthe bolster in the rail and with the spindle.

In Fig. 3 the holder (shown asa rod or cord) is attached to a like stud, b', and is then eX- tended over a pulley, b4, having its axis supported in a hanger, b5, the said holder having iOO applied to its outer end a weight, fw", the holder being extended, as shown hy dottedlines in Fig. 3 and by full lines in Fig. 4, through a slot in the shank e of the bolster.

In Fig. 5 the lower end of the, bolster is notched at opposite sides, or slabbed or out away to receive within said space the two holders b b, (shown best in Fig.'6,) one holder normally resting near or quite close to one of the Slabbed or cutaway paris of the foot c of the bolster C, the other holder lying opposite it and near or close to the other ent-away por tion ofthe foot ofthe bolster.

In Figs. 7 and S I have shown two holders, b b, preferably of wire, which are made to cooperate with a slabbed or notched part ofthe flange or collar a, all the said holders acting substantially alike with relation to the foot of the bolster, one holder cooperating with two or more holsters.

It is obvious that all the holsters of a spin ning-frame of any length may be made to cooperate with one single holder, thus providing aY-very cheap and at the same time an eil'ective cushion or check for any undue movement of the bolster.

In the modification, Fig. 9, the sleevewhirl is fastened to the spindle below the bolster-rail, and below the bolster-bearing the weight ot' the spindle is sustained by means of a collar,

1), which is screwed or otherwise fastened to the spindle at a point above the collar a of the bolster.

Myinvention is also applicable to not only cushion the movement ofa bolster of this class,

collar a, or it may be placed at a point below the rail A, a flexible holder, substantially such as shown and before described.

Priorto myinvention lam awarethata bolster and also a step has been mounted in a rail in such manner that it may tip slightly about a ledge or seat between the ends of the bolstei` or step, the bolster or step being kept pressed close in its seat by a spring-rod located immediately opposite the seat; but such spring-rod does not act as a cushion for a bolster placed in a rail in such manner as to have a limited extent of unrestrained lateral movement. So,

also, I am aware that a spindle-bolster having its shank extended loosely through a hole in a rail has been provided with au arm having an adjusting device, a spring being interposed between the said arm and rail to keep the whirl of the spindle inserted in the said bolster pressed properly into the band to keep it taut.

I claim`- The sleeve-whirl spindle and bolster-.rail provided with a hole and a bolster having its shank extended thereinloosely, combined with a ilexible holder adapted to engage the bolster at a point outside of the said rail and prevent the rotation of the said bolster in the said rail, substantially as described.

Intestilnonywhereof Ihave signed my naine to thisspecitication in the presence of two subscribing witnesses.
